TERMINAL FOR ELECTRIC WIRES.

Specification of Letters Patent.

Patented Dec. 8, 1908.

Application filed February 6, 1908. Serial No. 414,476.

To all whom it may concern:

Be it known that I, BERNARD Moncxn, a subject of the King of Great Britain, and a resident of Newport, in the county of Newport and State of Rhode Island, have invented a new and Improved Terminal for Electric \Vires, of which the following is a full, clear, and exact description.

This invention relates to certain improvements in terminal tips for electric wires, and more particularly to that type of tip formed of a single piece of sheet metal, so shaped as to constitute means for firmly securing the .t-ip to the wire or other conductor, and also for detachably securing the tip to a spark plug, binding post, or other conductor, to which the electric current is to be delivered.

The object of the invention is to provide an improved form of tip, whereby the liability of the tip becoming detached from the conductor is reduced to a minimum, in which extensive contact is made between the condoctor and the tip, and in which the tip may be readily secured to or detached from a binding post or the like, without the aid of any wrench, clamp, or other tool.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding pa rls in all the figures, and in which Figure 1 is a side elevation of a tip constructed in accordance with my invention, and serving to connect an insulated wire to a binding post; Fig. 2 is a longitudinal section of the same; Fig. 3 is a view of the blank from which the tip is formed; and Fig. 4 is an end elevation of the tip showing the conductor in cross. section.

My improved tip is preferably cut from sheet metal and so shaped as to form a central body ortion 10, of a size dependent upon the diameter of the conductor in connection with-which the tip is to be employed, and extending from opposite sides of this central portion are two wings 11 and 19. These two wings are substantially identical and each carries two fingers extending from opposite sides thereof. The two lingers 13 and. 14 of the wing 11 are in alinemcnt with each other and parallel to the two fingers 15 and 16 of the wing 12. Extending outwardly from opposite sides of the central body portion 10.are two spring clamping members 17 and 18, the members being of substantially the same width, but the member 18 is preferably somewhatlonger than the member 17. In the center of the body portion is an opening 19 for receivii'ig the strands of the conductor, and the two wings have openings 20 and )1 for receiving a portion of the strands. The two clamping members 17 and 18 have openings 22 and 23 for the reception of the binding post or other part to which the terminal is to be connected.

The tip is especially adapted for use with conductors in which thereare a plurality of strands A, inclosed by a heavy jacket B of insulating material. In applying the tip, the insulating jacket is cut away from the end of the conductor. so as to expose the strands for a short distance, and all of the strands are extended through the opening 1.) of the body portion of the tip, said body portion lying in a plane at right angles to the general direction of the conductor and seating against the end of the insulating jacket. The strands are then separated into two bunches G and D, and one of these bunches,

C, is returned through the opening 21 in the wing 12 of the tip, and the other bunch, D, is returned through the opening 20 of the wing ll of the tip. The two wings are then bent backwardly into engagement with the sides of the conductor and serve to clamp the terminal. portions of the strands between the wings and the jacket, and to conceal and protect the free ends of said strands. The fingers of each of the strands are then bent, so as to conform to the contour of the jacket and to hold the tip securely to the conductor and hold the central body portion rigidly against the end of the insulating jacket.

The two clamping members 17 and 18 are bent outwardly to form a loop with the ends of the two members overlapping but with the openings 22 and 23 out of alinement. By pressing on the two members the size of the loop may be reduced and the openings brought into alinement, so that they may he slipped over the end of a binding post or other terminal of a like nature. The clamping members normally tend to straighten out to a limited extent, or rather to enlarge the size of the loop, and this causes the edges of the openings to bindingly engage with opposite sldes of the binding post and to hold the tip securely thereon.

Having thus described my invention, I

.claim as new and desire to secure by Letters a and adapted to grip the conductor therebetween, and two spring clamp portions extending from opposite sides of said central portion intermediate said wing portions and ada ted to engage with a binding post or the he 4 2; A terminal tip for electric conductors, formed of sheet metal and comprising a central body portion adapted to extend transversely across the end of the conductor,-

meansintegral therewith for securing said body portion to said conductor, and oppositely-disposed sprin clamps extending from opposite sides of sai body portion and having their ends perforated and overlapping to enga 'e with a binding post or the like, when said perforations are in. alinement.

3. A terminal tip for electric conductors, formed of sheet metal and comprising a central body portion adapted to extend transversely across the end of the conductor, wing portions extending outwardly from opposite sides thereof, oppositely-disposed fingers carried by said wings, said wings adapted to engage with said conductor upon opposite sides thereof, and said fingers adapted to encircle said conductor, and means carried by said body portion and adapted to engage with a bindlng post or the like.

4. A terminal tip for electric conductors, formed of sheet metal, and comprising a central body portion adapted to extend transversely of the conductor and having a central aperture therein through which said conductormay pass, and wing portions carr1-ed by said "body portion upon opposite sides thereof and each having an aperture therein through which portions of said condoctor may pass, said Wing portions being adapted to engage with said conductor upon opposite sides to secure the ti to the conductor and cover the termmal portions thereof.

5. A terminal tip for insulated electric wires, said tip comprising a central body portion adapted to engage with the end of the insulation and having a central aperture "through which the wire or wires may pass,

and Wing portions carried by said body portion upon opposite sides thereof and each having an aperture therein through which the terminal portions of the wire may pass into engagement with the outer surface of the insulation, said wing portions adapted to clamp the terminal portions of the wire to said insulation and to engage with said insulation upon opposite si es thereof to hold said tip secure y in place.

6. A terminal 'tip for insulated wires, said tip being formed of sheet metal and comprising a central portion adapted to extend transversely of the general direction of said insulatedwires and in engagement with the terminal end of the insulation thereof, said central portion having an aperture therein through which said Wires may pass, wing 'ortions each havin an a erture therein P 7 a through Which said wires may again pass, said wlng portions serving to bmd the ter- '1ninal portions of said wires against the outer surface of said insulation, and sprin clamping portions earned by sa1d centra body portion at opposite sides thereof and intermediate said wing portions, and adapt,- ed to engage with a binding post or the like upon opposite sides thereof to secure said tip to the latter.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
